Structure for attaching dust collection electrode of wet electric dust collector

Abstract

A structure for attaching a dust collection electrode of a wet electric dust collector that is low-cost and resistant to entire face corrosion, space corrosion, and hole corrosion. An end of a dust collection electrode element is tightened and slung to be supported by a slung beam slung in a lateral direction in a building accommodating a dust collection apparatus. A supporting member made of Hastelloy® is attached to the dust collection electrode element. The supporting member and the slung beam include attachment holes through which the supporting member and the slung beam are tightened together by a bolt and nut. The slung beam and the dust collection electrode element have therebetween the supporting member to sling and support the slung beam and the dust collection electrode plate so that the slung beam and the dust collection electrode plate are separated from each other.

1. A structure for attaching a dust collection electrode of a wet electric dust collector in which an end of a dust collection electrode plate made of stainless material is tightened at and is slung to be supported by a slung beam slung in a lateral direction in a building accommodating a dust collection apparatus, comprising:
 a supporting member that is attached to the dust collection electrode plate and that is made of Hastelloy®; and 
 a tightening means having attachment holes in the Hastelloy-made supporting member and the slung beam to tighten the Hastelloy-made supporting member and the slung beam together via the attachment holes, 
 wherein the slung beam and the dust collection electrode plate have therebetween the Hastelloy-made supporting member to sling and support the dust collection electrode plate by the slung beam so that the slung beam and the dust collection electrode plate are separated from each other. 
 
     
     
       2. The structure for attaching a dust collection electrode of a wet electric dust collector according to  claim 1 ,
 wherein the slung beam is made of Hastelloy. 
 
     
     
       3. The structure for attaching a dust collection electrode of a wet electric dust collector according to  claim 1 , further comprising a plurality of said slung beams,
 wherein the Hastelloy-made supporting member is formed as a plate member, both faces of edges of the dust collection electrode plate are joined and welded to the Hastelloy-made supporting member, these joint parts are sandwiched between the slung beams, and these sandwiched parts are penetrated by attachment holes and are tightened together by the tightening means. 
 
     
     
       4. The structure for attaching a dust collection electrode of a wet electric dust collector according to  claim 1 , further comprising a plurality of said slung beams,
 wherein the Hastelloy-made supporting member is formed as a cylindrical boss and is caused to penetrate the attachment hole of the dust collection electrode and is welded and an end face of the cylindrical boss is sandwiched between the slung beams and is tightened by the tightening means via a boss hole. 
 
     
     
       5. The structure for attaching a dust collection electrode of a wet electric dust collector according to  claim 1 , further comprising a plurality of said slung beams,
 wherein the Hastelloy-made supporting member is welded to edges of the dust collection electrode plate to protrude to upper and lower sides, this protruding supporting plate is sandwiched between the slung beams and the protruding supporting plate and the slung beams are tightened together by the tightening means via the attachment holes penetrating the sandwiched part. 
 
     
     
       6. The structure for attaching a dust collection electrode of a wet electric dust collector according to  claim 1 , further comprising a plurality of said slung beams,
 wherein the structure is composed of a plate body for sandwiching the Hastelloy-made supporting member between the slung beams and a receiving member of the plate body welded to an edge of the dust collection electrode plate, the plate body and the receiving member have therebetween a removable mechanism. 
 
     
     
       7. The structure for attaching a dust collection electrode of a wet electric dust collector according to  claim 1 , further comprising a plurality of said slung beams,
 wherein a receiving member facing the attachment hole is attached to an end plate face of the dust collection electrode plate, the Hastelloy-made supporting member having the attachment hole is attached to this receiving member, the dust collection electrode plate is sandwiched between the supporting members from the outer faces of the supporting members and the dust collection electrode plate and the supporting members are tightened together by the tightening means. 
 
     
     
       8. The structure for attaching a dust collection electrode of a wet electric dust collector according to  claim 1 ,
 wherein the supporting member is surrounded by a resin sealing section to seal the supporting member.
